Intelligent Download of Application Programs

ABSTRACT

Improved techniques for controlling delivery (e.g., download) of application programs from a remote application repository to different client computing devices are disclosed. Application programs are often built to operate on computing devices that have certain hardware capabilities. Hence, application programs available for download from a remote application repository might not be suitable execution on all client computing devices that are able to access the remote application repository. The improved techniques for controlling delivery can operate to permit the applications to be received by only those client computing devices that have the required hardware capabilities to properly operate the application programs.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to download of applications programs and, more particularly, to managing download of application programs to different computing devices.

2. Description of the Related Art

Today, it is common for users to access on-line repositories to acquire digital media assets, such as songs, television shows and movies. More recently, on-line repositories have also supported download of application programs. The typical interaction with an on-line media repository is that a user will browse the on-line repository from a personal computing device, select one or more items to be downloaded, and then receive digital delivery of the items at the personal computing device via a network.

Computing devices take many different forms and have different functionalities and capacities. For example, computing devices can be wearable, hand-held, portable or desktop. The form factor and functionality of these computing devices also tend to be different. For example, desktop computers tend to have the most processing power and data storage capacity. Hand-held computing device are small and light weight but tend to lack the high processing power and data storage of desktop computers. Different computing devices of the same form factor can even have different capabilities depending on hardware components (e.g., GPS system, wireless communications, microphone, speaker, etc.) and/or software components (e.g., operating system).

Given the wide variety of computing devices, application programs are typically built to operate on certain hardware and software platforms. When such applications are provided to an on-line repository for distribution, the applications are available for download to others regardless of their hardware platform and/or software platform. While an on-line repository could display information about required minimum hardware and/or software components for an application program, users might still download the application program onto computing devices that lack the required minimum hardware and/or software components. As a result, the application program would not function properly, if at all, on the computing devices. Consequently, users are dissatisfied with the application program even through the problem results from users' computing devices not the application program.

Thus, there is a need for improved approaches to manage download of application programs to compatible computing devices.

SUMMARY OF THE INVENTION

The invention pertains to controlled application delivery (e.g., download) from a remote application repository to different client computing devices. Application programs are often built to operate on computing devices that have certain hardware and/or software capabilities. Hence, application programs available for download from a remote application repository might not be suitable execution on all client computing devices that are able to access the remote application repository. According to one aspect, the invention can operate to permit only those client computing devices that have the required hardware and/or software capabilities to receive the application programs. In one embodiment, restrictions imposed can allow users of client computing devices to view information about the application programs but prevent download to those client computing devices lacking the required hardware and/or software capabilities. In another embodiment, warnings imposed can allow users of client computing devices lacking the required hardware and/or software capabilities to be warned prior to downloading of application programs to those client computing devices. In still another embodiment, restrictions imposed can filter availability of information about application programs available from the remote application repository such that users can only view information regarding those applications they are able to download onto such client computing devices.

DETAILED DESCRIPTION OF THE INVENTION

The invention pertains to controlled application delivery (e.g., download) from a remote application repository to different client computing devices. Application programs are often built to operate on computing devices that have certain hardware and/or software capabilities. Hence, application programs available for download from a remote application repository might not be suitable execution on all client computing devices that are able to access the remote application repository. According to one aspect, the invention can operate to permit only those client computing devices that have the required hardware and/or software capabilities to receive the application programs. In one embodiment, restrictions imposed can allow users of client computing devices to view information about the application programs but prevent download to those client computing devices lacking the required hardware and/or software capabilities. In another embodiment, warnings imposed can allow users of client computing devices lacking the required hardware and/or software capabilities to be warned prior to downloading of application programs to those client computing devices. In still another embodiment, restrictions imposed can filter availability of information about application programs available from the remote application repository such that users can only view information regarding those applications they are able to download onto such client computing devices.

Embodiments of the invention are discussed below with reference to FIGS. 1-7C. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.

FIG. 1 is a block diagram of an application distribution system 100 according to one embodiment of the invention. The application distribution system 100 includes an on-line media repository 102 that couples to a network 104 so as to allow a plurality of computing devices 106 to interact with the on-line media repository 102. The on-line media repository 102 can be implemented by a single server computer or distributed over multiple server computers. In one implementation, the network 104 can refer to one or more data networks, typically, high data-bandwidth networks, namely, wired networks, such as the Internet, Ethernet, gigabit Ethernet, and fiber optic, as well as wireless networks such as IEEE 802.11(a),(b) or (g) (WiFi), IEEE 802.16 (WiMax), and Ultra-Wide Band (UWB).

The on-line media repository 102 stores a plurality of application programs 108. These application programs 108 can be computer programs that operate on some or all of computing devices 106. Developers can produce application programs and submit them to the on-line media repository 108 for distribution. Here, the on-line media repository 108 can serve to store and distribute a large number of application programs. The computing devices 106 can have different form factors and capabilities. For example, as shown in FIG. 1, the computing device 106 can pertain to a portable computer 106-1, hand-held computer or personal digital assistant (PDA) 106-2, mobile phone 106-3 (e.g., cellular phone), or set-top box 106-4.

According to one embodiment of the invention, to distribute the application programs 108 from the on-line media repository 102 in an improved manner, the on-line media repository 102 stores supported device requirements (SDRs) 110 for some or all of the application programs 108. The supported device requirements 110 can be defined by the developer and provided to the on-line media repository 102 when providing the application program 108. The supported device requirements 110 pertained to minimum device requirements that any computing device 106 must have in order for the application program 108 to properly operate on the computing device 106. As an example, the on-line media repository 102 can limit distribution of the application programs 108 to only those of the computing devices 106 that meet the supported device requirements 110. In one embodiment, the on-line media repository 102 can enforce the supported device requirements 110 for the application programs 108.

The computing device 106 can include device information 112. The device information 112 can pertained to the device capabilities of the computing device 106. Hence, when the user of the computing device 106 accesses the on-line media repository 102 via the network 104, which can pertained to the Internet, the computing device 106 can initially receive information descriptive of the one or more application programs 108 available from the on-line media repository 102. Through user interaction with the computing device 106, the user can navigate through the information descriptive of the one and more application programs 108 available from the on-line media repository 102 to select a particular application program 108 that the user desires to receive at the computing device 106. Together with the information descriptive of the one and more application programs 108, the computing device 106 can also receive supported device requirements 110′. In the event that the user requests to receive the particular application program 108, the computing device 106 can operate to evaluate whether the computing device 106 is able to adequately support the particular application program 108. In one embodiment, the computing device 106 compares the supported device requirements 110′ with the device information 112 to determine whether the computing device 106 is able to adequately support the particular application program 108. If the computing device 106 determines that the computing device 106 is able to adequately support the particular application program, the particular application program 108 can be downloaded from the on-line media repository 102 through the network 104 to the computing device 106. Thereafter, the application program 108 can be installed to become an installed application program 108′ on the computing device 106.

FIG. 2 is a flow diagram of an application acquisition process 200 according to one embodiment of the invention. The application acquisition process 200 is, for example, processing performed at a computing device to determine whether a user requesting an application program is permitted to acquire the application program.

The application acquisition process 200 can support 202 user navigation of available application programs. The user navigation of the available application programs allows a user to identify a specific application program that they desire to acquire or install. Following the support 202 for the user navigation in which a specific application program is identified, a decision 204 can determine whether a user acquisition request for a specific application program has been received. When the decision 204 determines that a user acquisition request has not been received, the application acquisition process 200 can return to repeat the block 202. Alternatively, when the decision 204 determines that a user acquisition request for a specific application program has been received, device capabilities for a client device to receive the specific application program can be retrieved 206. Typically, the client device stores its device capabilities in an accessible data storage region within the client device. The client device can store its device capabilities directly or can store a type indicator that represents or references device capabilities for the client device.

Next, a decision 208 determines whether the client device supports operation of the specific application program. Here, through use of the device capabilities for the client device, the application acquisition process 200 can evaluate whether the client device supports operation of the specific application program. When the decision 208 determines that the client device does not support operation of the specific application program, an indication that the acquisition request is denied can be presented 210. On the other hand, when the decision 208 determines that the client device does support operation of the specific application program, the acquisition request for the specific application program can be processed 212. As a result of the processing 212 of the application request, the specific application program is delivered to the client device. Once the specific application program is provided to the client device, the client device can install and utilize the specific application program. Following the blocks 210 or 212, the application acquisition process 200 can end.

FIG. 3 is a flow diagram of an application acquisition process 300 according to one embodiment of the invention. The application acquisition process 300 can, for example, be performed by a client device. The client device is a computing device capable of executing computer programs. For example, the application acquisition process 300 can be performed by any of the computing devices 106 illustrated in FIG. 1.

The application acquisition process 300 can access 302 an on-line application repository that stores a plurality of application programs that are available for distribution. As one example, the on-line application repository can pertain to the on-line media repository 102 illustrated in FIG. 1. The on-line application repository can then be navigated 304. Through the navigation 304, application information for at least one application program can be displayed 306. For example, the application information can be displayed on a display device associated with the computing device. The application program has supported device requirements for the application program. The supported device requirements can pertain to minimum hardware and/or software components for a computing device to properly operate the computing device. For example, the minimum hardware requirements might require the computing device to have hardware components, such as a GPS system, a wireless communications, a microphone, a speaker, etc., and the minimum software requirements might require that the computing device have software components, such as a particular operating system. The supported device requirements can be contained within the application information or otherwise associated with the application program. For example, the application information can be provided as a markup language page, such as a webpage, that contains a description (e.g., XML description) of the supported device requirements.

Next, a decision 308 can determine whether an acquisition request has been received. When the decision 308 determines that an acquisition request has not been received, the application acquisition process 300 can return to repeat the block 304 and subsequent blocks so that the navigation 304 of the on-line application repository and the display 306 of application information can continue.

On the other hand, once the decision 308 determines that an acquisition request has been received, device information for the client device can be retrieved 310. The device information for the client device describes (directly or indirectly) the device functionalities for the client device. The device information can be compared 312 to the supported device requirements for the application program. Based on the comparison 312, a decision 314 can determine whether the application program is supported by the client device. When the decision 314 determines that the application program is not supported by the client device, an indication that the acquisition request is denied can be presented 316. Alternatively, when the decision 314 determines that the application program is supported by the client device, the acquisition request for the specific application program can be processed 318, whereby the specific application program can be received at the client device from the on-line application repository. Following the blocks 316 or 318, the application acquisition process 300 can end.

FIG. 4 is a flow diagram of an application download process 400 according to one embodiment of the invention. The application download process 400 is, for example, performed by a computing device, such as any of the computing devices 106 illustrated in FIG. 1.

The application download process 400 can display 402 an application description page. The application description page can be provided by an on-line applications store that is hosted by a remote server. For example, the on-line media repository 102 can pertain to a remote server that hosts an on-line applications store. The application description page can pertain to a markup language page, such as a webpage, that can be displayed by a program or browser operating at the computing device. The application description page provides a description of a particular application program and also includes one or more user interface controls, such as virtual buttons. At least one of the virtual buttons is a download button that, on selection, requests to download the application program from the remote server to the computing device. Following the display 402 of the application description page, a decision 404 determines whether a download button on the application description page has been selected. When the decision 404 determines that a download button has not been selected, other processing 406 can be optionally performed before the application download process 400 returns to repeat the block 402 so that the user can continue to review and interact with the application description page.

On the other hand, when the decision 404 determines that a download button has been selected, embedded code in the application description page can be executed (including interpreted) 408 to determine whether the application program is supported by the computing device (client device) performing the application download process 400. A decision 410 can then determine whether the application program is supported by the computing device. Here, it is determined using the embedded code whether the particular application program is supported by the computing device. In one implementation, the supported device requirements provided with the application description page can be checked against device information known by the computing device. As one example, the embedded code can be provided in a scripting language, such as JavaScript. When the decision 410 determines that the application program is not supported, download of the application program can be denied 412. In this case, since the application program cannot properly be utilized on the computing device, the download request made by the selection of the download button is denied 412. Alternatively, when the decision 410 determines that the application program is supported, download of the application program to the computing device can be processed 414. Following the blocks 412 or 414, the application download process 400 can end.

FIG. 5 is a flow diagram of an application availability process 500 according to one embodiment of the invention. The application availability process 500 can be utilized to render application programs available for distribution by an on-line application repository. For example, the on-line application repository is, for example, the on-line media repository 102 illustrated in FIG. 1.

The application availability process 500 initially begins with an application program being developed 502. Here, a software developer can develop an application program to be utilized on a computing device. Next, the application program can be submitted 504 along with supported device requirements to an on-line application repository. The developer submits 504 application program to the on-line application repository so that the on-line application repository can assist the developer with distribution of the application program to numerous users. By providing the supported device requirements, the developer can thus inform the on-line application repository of the requirements on the computing device in order for the application program to operate properly.

Once the application program has been submitted 504, a decision 506 can determine whether the application program is approved for distribution. Here, the on-line application repository can perform one or more manual or automated checks or evaluations to determine whether the application program is suitable for distribution via the on-line application repository. When the decision 506 determines that the application is not approved for distribution, a decision 508 can determine whether the submission is to be retried. When the decision 580 determines that the submission is to be retried, the application availability process can return to repeat the block 504 so that the developer can again submit 504 the application program to the on-line application repository. Here, the developer is able to make another attempt to have the application program approved for distribution by the on-line application repository. Hence, the developer may be able to correct defects in their earlier submission and then resubmit their application program to the on-line application repository.

On the other hand, when the decision 506 determines that the application program has been approved for distribution, the application program is rendered 510 available for distribution at the on-line application repository. This allows various users of computing devices to interact with the on-line application repository to acquire the application program. Following the block 510, or following the decision 508 when the submission is not to be retried, the application availability process 500 can end.

FIG. 6 is a flow diagram of an application download process 600 according to one embodiment of the invention. The application download process 600 can, for example, be performed by a client device. The client device is a computing device, such as any of the computing devices 106 illustrated in FIG. 1.

The application download process 600 can access 602 an on-line application repository. Once the on-line application repository has been accessed 602, the on-line application repository can be navigated 604 by a user of the computing device to select an application program to be downloaded. Upon selecting an application program, application information pertaining to the selected application program can be displayed 606. The application information can include at least text and/or graphic that explains, characterizes or describes the application program. Next, a decision 608 determines whether a download request has been received for the selected application program. When the decision 608 determines that a download request has not been received, the application download process 600 can return to repeat the block 604 so that the navigation 604 and the display 606 can continue.

On the other hand, when the decision 608 determines that a download request has been received, a device type for the client device can be retrieved 610. The device type is associated with a particular class or category of client devices that might interact with the on-line application repository to download application programs. A decision 612 can then determine whether the device type for the client device is a supported device type for the selected application program. When the decision 612 determines that the device type for the client device is not a supported device type for the selected application program, a message indicating that the download request is denied can be displayed 614. Alternatively, when the decision 612 determines that the device type is a supported device type for the selected application program, download of the selected application program to the client device can be permitted 616. Following the blocks 614 or 616, the application download process 600 can end.

In the application download process 600, a device type for the client device can be retrieved 610. The device type denotes those device types that are compatible with a selected application program. The device type can, for example, represent a certain set of supported device requirements. In one embodiment, the application information for the selected application program that is provided to the client device is a markup language document, such as a web page, that includes an indication of the supported device types. Additionally, for each supported device type, the markup language document can specify one or more of: a device type ID, minimum product version, minimum product version title, minimum product version description, minimum device title, or minimum device description. If the client device is of a type equal to one of the supported device types and the product version of the client device is greater than or equal to the minimum product version, then the selected application program is deemed compatible for use on the client device.

Alternatively, if the client device is of a type equal to (i.e., matches) one of the supported device types but the product version of the client device is less than the minimum product version, then the selected application program is deemed not compatible for use on the client device. In this case, the minimum product version title and/or minimum product version description can be used to form a notification that is presented by the client device. As an example, the notification can inform the user that the client device does no support the selected application program, e.g., “Application Not Compatible”, and also provide a reason, e.g., “The application requires a software update on your device”. For example, the software update could pertain to an operating system update for the client device. The minimum product version can also pertain to a product version or an operating system version. In one embodiment, the minimum product version title and/or minimum product version description can include a universal resource location (URL) to specify a location for additional information on the incompatibility or for a location to acquire the required component(s).

In another alternative, if the client device is of a type not equal to any of the supported device types, then the selected application program is deemed not compatible for use on the client device. In this case, the minimum device title and/or minimum device description can be used to form a notification that is presented by the client device. As an example, the notification can inform the user that the client device does not support the selected application program, e.g., “Application Not Compatible”, and also provide a reason, e.g., “The application cannot be used on this device, it requires device x or device y”. In one embodiment, the minimum device title and/or minimum device description can include a universal resource location (URL) to specify a location for additional information on the incompatibility or for a location to acquire the required component(s).

In still another alternative, regardless of whether the client device is of a type matching any of the supported device types, a client device of a certain type or serial number could be prevented from being deemed compatible. In such case, the selected application program would be deemed unavailable to the client device. In this case, a notification can be presented by the client device. As an example, the notification can inform the user that the selected application program is not available for use on the client device. In one embodiment, the notification can include a universal resource location (URL) to specify a location for additional information on the unavailability.

FIGS. 7A-7C are exemplary screen depictions of web pages according to embodiments of the invention. The web pages are provided by an application distribution website hosted by or coupled to an on-line repository and presented on a display device of a client computing device.

FIG. 7A illustrates an exemplary screen depiction of a web page 700 pertaining to an application program according to one embodiment of the invention. The web page can be produced by the processing noted above. As an example, the web page can represent one implementation of application information provided in FIG. 3 or 6, or can represent one implementation of an application description page provided in FIG. 4. The web page 700 can include an application characteristics section 702 that lists characteristics or details of the application program. The characteristics or details can specify one or more of title, category, released date, seller name, version number, size (e.g., in MBs), price and rating. The web page 700 can also include a graphic for the application program, such as a cover image, logo or the like. In addition, the web page 700 can include a “Get App” button 706 that, upon user selection, requests download (or acquisition) of the application program from the on-line repository. The web page 700 can also present one or more representative screens 708 pertaining to the application program. The web page 700 can also include an application description that provides a textual description of the application program. Still further, the web page 700 can include other information, such as customer reviews, pertaining to the application program.

FIG. 7B illustrates an exemplary screen depiction of a web page 720 according to one embodiment of the invention. The web page 720 can be displayed on the client computing device when the requested application program is not permitted to be downloaded to the client computing device. Specifically, as noted above, in response to requesting download of an application program to a client computing device, it can be determined whether the client computing device is able to properly operate the application program. In this embodiment, the web page 720 displays a notification 722 that informs a user of the client computing device that download of the application program is not permitted on the client computing device. In the particular example illustrated in FIG. 7B, the notification displayed states “Sorry, your client device is not compatible with this application”. In FIG. 7B, the notification 722 is displayed at the top portion of the web page 720. For example, the web page 720 can result by updating the web page 700 shown in FIG. 7A by inserting the notification 722 at the top of the displayed page. However, in other embodiments, the notification can be displayed anywhere on the web page 720 or in another window (e.g., dialog box). In still another embodiment, the notification can be presented in an audio manner (with or without also displaying the notification 722).

FIG. 7C illustrates an exemplary screen depiction of a web page 740 according to one embodiment of the invention. The web page 740 can be displayed in the client computing device when the requested application program is not permitted to be downloaded to the client computing device. Specifically, as noted above, in response to requesting download of an application program to a client computing device, it can be determined whether the client computing device is able to properly operate the application program. In this embodiment, the web page 740 blocks the user of the client computing device from being able to request an application program that is not permitted to be downloaded to the client computing device. For example, the “Get App” button 706 that, upon user selection, requests download (or acquisition) of the application program from the on-line repository can be disabled. The disablement of the “Get App” button 706 can be visually identified. For example, the “Get App” button 706 is shown in FIG. 7C as being disabled by an “X” superimposed on the button graphics. In alternative embodiments, the “Get App” button 706 could be “Grayed out” to indicate it being inactive or could be completely removed from the web page 740.

The various aspects, features, embodiments or implementations of the invention described above can be used alone or in various combinations.

The invention is preferably implemented by software, hardware, or a combination of hardware and software. The invention can also be embodied as computer readable code on a computer readable medium. The computer readable medium is any data storage device that can store data which can thereafter be read by a computer system.
